4895 and 4064 are classic 308 powders. I can't imagine a circumstance where I'd use 4350 though.
Do you like to throw powder charges? 4064 is great but it's a pain in most powder measures. With my bolt action 308s it's easy to get sub-moa results with IMR4895. With LC match brass that has been sorted for neck thickness uniformity I have my Model 700 VTR shooting 1" ten shot groups with thrown charges of 42 grains of IMR4895 and 168 grain Nosler match bullets. This is with ambient temperatures between 55 and 60 degrees F and no pause for barrel cooling.
